Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

This substance is a reaction mass of dipropylene glycol dibenzoate (DPGDB), diethylene glycol dibenzoate (DEGDB) and triethylene glycol dibenzoate (TEGDB). No testing has been performed on the reaction mass itself but data are available for DPGDB, DEGDB and TEGDB individually. All the studies were performed according to international test guidelines and in compliance with GLP.  The acute toxicity studies were carried out on Daphnia magna.  These data demonstrate that the components of the reaction mass have similar environmental profiles with all EC50 values in the same order of magnitude, >1.0 mg/L and <10 mg/L. The most sensitive endpoint result obtained for these components has been used as the key value to evaluate hazard and is highlighted below.

The key value is:

Aquatic toxicity to aquatic invertebrates EC50 = 3.05 mg/L (DEGDB)
